Optimum software package for on-line system management and job accounting

Abstract

An access control mechanism is a set of operations performing auth<>- rization and enforcement checks, creation and movement of rights within the system from assigned control functions established by predefined control information. Enforcing accec,Scontrol policies, which are the basis of control information, requires knowing who can access, is a total reflection of management policies of a computing system. MeasureS of access validation, to S,OTIeextent, is optional and in actuality, is dominated and modulated by the management policies of the authority of a computing system. An online software control mechanism for the management of computer systems has been developed in order to validate a user's access into the system on extensive measureS of constraints. System management operations for process control of different job requeSts are attributed and realized, to some extents, in the form of controlling priority attribute through modifications, and servicing the timer interrupt requests with job termination "ftcr a definite interval of processing time. To make the enforcement of acceSS control and proceSS control policies, a secondary storage base for control information is maintained with many oth"r as,;ociat()d or supporting information like job stati5tics or job accounting information to ensure proper decisive actions. The complete software system has been developed in IBM/370 and a specific version of this has been installed irithe same operated under DOS/VS and also in IBM/4331 operated under OOS/VSE in BUET Computer Centre.
